Nonentity

J. Van der Geer’s 2000 paper “The Art of Writing a Scientific Article” has been cited more than a thousand times, yet it doesn’t exist. Neither does the journal it appears in, the Journal of Science Communications.

The original was a “phantom reference” that had been presented only to illustrate Elsevier’s desired reference style. It seems to have been picked up by authors who didn’t understand that it was only a template, or who’d inadvertently retained the template while using it to format the rest of their references.

Anne-Wil Harzing, a professor of International Management at at Middlesex University in London, who described the confusion on her blog, concluded that the mystery “ultimately had a very simple explanation: sloppy writing and sloppy quality control.”

A Different View

Manet’s painting A Bar at the Folies-Bergère is sometimes criticized for its confused composition. The bottles to the barmaid’s right stand near the back of the bar, but in the reflection behind her they stand near the front. Her own image ought to stand behind her, not off to the right. And reflection of the man she’s addressing (in the position of the painter, or the viewer) ought also to be behind her — indeed, she herself should be blocking our view of it.

But in a dissertation at the University of New South Wales, art historian Malcolm Park found that the arrangement makes sense if certain assumptions are reconsidered. The barmaid is facing the viewer across the bar, with a mirror behind her. But she’s looking diagonally along the bar, not directly across it. (See the diagram here.)

The bottles in the background and the man she appears to be addressing are both in fact to the viewer’s left, beyond the edge of the frame and so visible only as reflections. And the barmaid’s own reflection appears to our right because, from our perspective, the mirror is not directly behind her — it’s “turned” somewhat, carrying her image over to one side.

Locke’s Index

https://archive.org/details/gu_newmethodmaki00lock

Like many thinkers of his age, John Locke maintained a commonplace book, an intellectual scrapbook of ideas and quotations he’d found in his readings. In order to be useful, such a book needs an index, and Locke’s method is both concise (occupying only two pages) and flexible (accommodating new topics as they come up, without wasting pages in trying to anticipate them).

The index lists the letters of the alphabet, each accompanied by the five vowels. Then:

When I meet with any thing, that I think fit to put into my common-place-book, I first find a proper head. Suppose for example that the head be EPISTOLA. I look unto the index for the first letter and the following vowel which in this instance are E. i. If in the space marked E. i. there is any number that directs me to the page designed for words that begin with an E and whose first vowel after the initial letter is I, I must then write under the word Epistola in that page what I have to remark.

The result is a useful compromise: Each of the book’s pages is put to productive use without any need for an overarching plan, and the contents are kept accessible through a simple, expanding index that occupies only two pages. The whole project can grow in almost any direction, and when the pages are full then a new volume can be begun.

All Together Now

In 1833, Heinrich Scherk conjectured that every prime of odd rank (accepting 1 as prime) can be composed by adding and subtracting all the smaller primes, each taken once. For instance, 13 is the 7th prime and 13 = 1 + 2 – 3 – 5 + 7 + 11.

In 1967 J.L. Brown Jr. proved that this is true.

Podcast Episode 330: The Abernathy Boys

https://commons.wikimedia.org/wiki/File:Abernathy_3641566828_cfa488c790_o.jpg

In 1909, Oklahoma brothers Bud and Temple Abernathy rode alone to New Mexico and back, though they were just 9 and 5 years old. In the years that followed they would become famous for cross-country trips totaling 10,000 miles. In this week’s episode of the Futility Closet podcast we’ll trace the journeys of the Abernathy brothers across a rapidly evolving nation.

We’ll also try to figure out whether we’re in Belgium or the Netherlands and puzzle over an outstretched hand.

One Nation, Indivisible

The second professor of mathematics in the American colonies suggested reckoning coins, weights, and measures in base 8.

Arguing that ordinary arithmetic had already become “mysterious to Women and Youths and often troublesome to the best Artists,” the Rev. Hugh Jones of the College of William and Mary wrote that his proposal was “only to divide every integer in each species into eight equal parts, and every part again into 8 real or imaginary particles, as far as is necessary. For tho’ all nations count universally by tens (originally occasioned by the number of digits on both hands) yet 8 is a far more complete and commodious number; since it is divisible into halves, quarters, and half quarters (or units) without a fraction, of which subdivision ten is uncapable.”

Successive powers of 8 would be called ers, ests, thousets, millets, and billets; cash, casher, and cashest would be used in counting money, ounce, ouncer, and ouncest in weighing, and yard, yarder, and yardest in measuring distance (so “352 yardest” would signify 3 × 82 + 5 × 8 + 2 yards).

Jones pressed this system zealously, arguing that “Arithmetic by Octaves seems most agreeable to the Nature of Things, and therefore may be called Natural Arithmetic in Opposition to that now in Use, by Decades; which may be esteemed Artificial Arithmetic.” But he seems to have had no illusions about its prospects, acknowledging that “there seems no Probability that this will be soon, if ever, universally complied with.”

(H.R. Phalen, “Hugh Jones and Octave Computation,” American Mathematical Monthly 56:7 [August-September 1949), 461-465.)
